Flutter 分析发现 Gitlab CI/CD 管道中存在本地未发现的问题

Question

我最近开始了一个新的 Flutter 项目。目前还没有什么可做的。只有几个文件和一些基本包(例如用于本地化的 Riverpod 和 intl)。

每当我在本地计算机上运行flutteranalyze时，我当前的分支上都没有问题。在 flutter clean 和 flutter pub get 等之后，这保持不变。

但是，当我将此分支提交并推送到 Gitlab 时，我在 CI 中调用的 flutteranalysis 确实产生了三个问题，这些问题似乎与无法找到或访问 intl 有关包。

这是我的 Gitlab CI 文件:

analyse:
    stage: test
    image: "cirrusci/flutter:stable"
    before_script:
    - export PATH="$PATH":"$HOME/.flutter-sdk/.pub-cache/bin"
    - flutter pub get
    - flutter --version
    script:
        - flutter analyze

test:
    stage: test
    image: "cirrusci/flutter:stable"
    before_script:
    - export PATH="$PATH":"$HOME/.flutter-sdk/.pub-cache/bin"
    - flutter pub get
    script:
        - flutter test -j 1 test

版本调用是为了确保 Gitlab 和本地中的 Flutter 和 Dart 版本相同。

这是分析阶段的输出:

这些问题都发生在主文件中，如下所示:

import 'package:flutter/material.dart';
import 'package:flutter_localizations/flutter_localizations.dart';
import 'package:flutter_riverpod/flutter_riverpod.dart';
import 'package:kook_app/ui/app/app_page.dart';

import 'l10n/l10n.dart';

void main() {
  runApp(const KookApp());
}

class KookApp extends StatelessWidget {
  const KookApp({super.key});

  @override
  Widget build(BuildContext context) {
    return ProviderScope(
      child: MaterialApp(
        localizationsDelegates: const [
          S.delegate,
          GlobalMaterialLocalizations.delegate,
          GlobalWidgetsLocalizations.delegate,
          GlobalCupertinoLocalizations.delegate,
        ],
        supportedLocales: const [
          Locale('en', 'UK'),
          Locale('nl'),
        ],
        debugShowCheckedModeBanner: false,
        title: 'KookApp',
        theme: ThemeData(
          primarySwatch: Colors.blue,
        ),
        home: const AppPage(),
      ),
    );
  }
}

该文件本身也不会报告 Android Studio 中的任何问题。

最后，为了完整起见，这是我的 pubspec:

您收到的错误:

  error • Target of URI doesn't exist: 'l10n/l10n.dart' • lib/main.dart:6:8 • uri_does_not_exist
  error • The values in a const list literal must be constants • lib/main.dart:20:11 • non_constant_list_element
  error • Undefined name 'S' • lib/main.dart:20:11 • undefined_identifier

在这里是因为 l10n/l10n.dart文件不存在。

我的猜测是你有这个文件，或者l10n/ .gitignore 中的目录，因此它不在存储库中，GitLab CI 也不会克隆它。

您有两个选择:

• 如果您仍然打算不保留l10n在您的存储库中，您需要运行 flutter gen-l10n在你的before_script ,
• 或删除 l10n您的 .gitignore 中的目录/文件并将其提交到存储库。
